As shоwn in Fig. 2, а l = 1 . 00 m lоng cоnducting rod in good contаct with а frictionless conducting frame moves to the left with a constant speed v → = 5 . 00 m / s . The light bulb in the conducting frame has a resistance of 12 . 00 Ω . The entire system is immersed in a magnetic field of magnitude B → = 9 . 00 × 10 3 G which is inclined at 30 . 00 ° with respect to the frame as shown in Fig. 2. (a) Find the induced electromotive force on the circuit. (b) What is the direction and magnitude of magnetic force exerted on the rod? (c) Calculate the electrical power dissipated in the light blub. (d) To maintain the rod’s constant speed v → = 5 . 00 m / s , an external force must be applied on the rod. Determine the work done by the external force after the rod is moved to the left for 3 . 00 m . The rod stops moving when the rod is 7 . 50 m from the left end of the frictionless frame but the magnitude of the magnetic field changes with time. (e) What is changing rate of the magnitude of the magnetic field so that the induced electromotive force is the same as the one in (a)? (Note: 1 G = 10 - 4 T ) fig2_q12_t3.jpg Fig. 2
